Help maintain your vehicle’s performance with regular check-engine light services


Today’s vehicles are smarter than ever and rely on sophisticated electronics and computer systems. Diagnosing your vehicle’s electrical problems often requires advanced, sensitive diagnostic equipment that the certified technicians at Tire & Service Network locations use to properly diagnose why your check-engine light is on. The check engine diagnostics service evaluates your vehicle’s:


  • Ignition system
  • Anti-lock brake system (ABS)
  • Restraint system
  • Fuel injection system
  • Emissions system
  • Electrical system

Check-engine light services are backed by the Tire & Service Network Limited Warranty.


Why is engine maintenance important for my vehicle’s performance?


Complex electrical problems may be almost impossible to diagnose without the help of engine diagnostics. In fact, engine diagnostic services are best way to pinpoint the reason for an illuminated and/or flashing check-engine light. These could include:


  • Your vehicle may have an engine, electrical, or computer performance issue
  • Your sensors or brake system may need to be reset or adjusted
  • You may be due for an oil change or other regularly scheduled engine maintenance

Do I need to have my engine serviced frequently?


Don’t wait until your check-engine light turns on. You should have a thorough engine diagnostic check at least once a year for optimal vehicle safety, reliability, and performance.


It’s important to get an engine diagnostic immediately if you experience any of the following:


  • Your check-engine light is flashing
  • Your check-engine light illuminates and remains on
  • One or more vehicle system sensor lights (tire pressure, etc.) turns on and won’t reset
  • Your vehicle is not performing well, even if no check engine light is on or flashing
